3. Setup Guide

3.1 Installing Switches and Keycaps

The Y75PRO features full key hot-swappable sockets, compatible with both 3-pin and 5-pin mechanical switches. This allows for easy customization without soldering.

1. **Prepare Switches**: Ensure your chosen mechanical switches are compatible (3-pin or 5-pin).
2. **Align Switches**: Carefully align the pins of the switch with the holes on the PCB. Ensure the switch is oriented correctly.
3. **Insert Switches**: Gently press the switch into the socket until it clicks into place. Do not force it to avoid bending pins.
4. **Install Keycaps**: Once all switches are installed, place your desired keycaps onto the switches.
